Multiple SSH keys for different github accounts

Multiple SSH Keys settings for different github account

create different public key

create different ssh key according the article Mac Set-Up Git

$ ssh-keygen -t rsa -C "your_email@youremail.com"

Please refer to github ssh issues for common problems.

for example, 2 keys created at:

~/.ssh/id_rsa_activehacker
~/.ssh/id_rsa_jexchan

then, add these two keys as following

$ ssh-add ~/.ssh/id_rsa_activehacker
$ ssh-add ~/.ssh/id_rsa_jexchan

you can delete all cached keys before

$ ssh-add -D

finally, you can check your saved keys

$ ssh-add -l

Modify the ssh config

$ cd ~/.ssh/
$ touch config
$ subl -a config

Then added

#activehacker account
Host github.com-activehacker
	HostName github.com
	User git
	IdentityFile ~/.ssh/id_rsa_activehacker
	IdentitiesOnly yes

#jexchan account
Host github.com-jexchan
	HostName github.com
	User git
	IdentityFile ~/.ssh/id_rsa_jexchan
	IdentitiesOnly yes

Clone you repo and modify your Git config

clone your repo git clone git@github.com-activehacker:activehacker/gfs.git gfs_jexchan

...or for an existing working directory git remote set-url origin git@github.com-activehacker:activehacker/gfs.git

cd gfs_jexchan and modify git config

$ git config user.name "jexchan"
$ git config user.email "jexchan@gmail.com" 

$ git config user.name "activehacker"
$ git config user.email "jexlab@gmail.com" 

or you can have global git config $ git config --global user.name "jexchan" $ git config --global user.email "jexchan@gmail.com"

then use normal flow to push your code

$ git add .
$ git commit -m "your comments"
$ git push

Command of "ssh-add -D" will DELETE all identities but not delete all cached keys before.
So, you should run "ssh-add -D" command first and "ssh-add ~/.ssh/id_rsa_activehacker" second.
